The motor control unit 17 restricts the output of the motor 3 to the second intermediate output until the pressing operation to the first pressing unit 11 is stopped if the pressing operation to the first pressing unit 11 is the operation in which the output of the motor 3 exceeds the second intermediate output from the state less than the second intermediate output that is equal to or greater than the first intermediate output and between the first intermediate output and the maximum output.SELECTED DRAWING: Figure 6

Description

[Technical Field]

[0001] The present invention relates to a motor control device, and more particularly to a motor control device and program for an electric reel that uses a motor to drive a spool rotatably attached to a reel body. [Background technology]

[0002] Among electric reels, there are known ones that use a pressure sensor in the operating part for changing the spool winding speed. For example, Patent Document 1 discloses an electric reel that changes the spool winding speed according to the pressure applied to the pressure sensor. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-337138 [Patent Document 2] Patent Publication No. 2021-016316 Summary of the Invention [Problem to be solved by the invention]

[0004] With the electric reel of Patent Document 1, particularly when adjusting the motor rotation speed in accordance with the pull of a fish, depending on the angler's posture holding the reel or the position of their fingers, a greater pressing force than intended may be generated, which could cause the motor rotation speed to increase to a speed higher than the angler anticipates. To prevent this, the electric reel of Patent Document 2 is set to an intermediate output so that the motor will only output up to the intermediate output with a single pressing. However, in this case, there is a risk that the output may be unintentionally increased to maximum output within the range above the intermediate output required for fighting with a fish.

[0005] An object of the present invention is to prevent the motor output from increasing more than the angler expects in a motor control device for an electric reel. [Means for solving the problem]

[0006] A motor control device for an electric reel according to one aspect of the present invention uses a motor to drive a spool rotatably attached to a reel body. The motor control device includes a first pressing unit and a motor control unit. The first pressing unit is provided on the reel body so as to be pressed. The motor control unit increases the output of the motor in accordance with at least one of a first pressing force applied to the first pressing unit and a pressing time for which the first pressing unit is pressed. If the pressing of the first pressing unit is an operation that causes the motor output to exceed the first intermediate output from a state where the motor output is less than the first intermediate output, the motor control unit limits the output of the motor to the first intermediate output until the pressing of the first pressing unit is stopped. If the pressing of the first pressing unit is an operation that causes the motor output to exceed the second intermediate output from a state where the motor output is equal to or greater than the first intermediate output and less than a second intermediate output between the first intermediate output and the maximum output, the motor control unit limits the output of the motor to the second intermediate output until the pressing of the first pressing unit is stopped.

[0007] In this motor control device for electric reels, when the motor output is less than the first intermediate output, the motor output will not increase above the first intermediate output even if the first pressing portion is pressed. Therefore, even if the first pressing portion is pressed with more force than intended when the motor output is less than the first intermediate output, the motor output is limited so as not to exceed the first intermediate output. This makes it possible to prevent the motor output from increasing more than the angler intended.

[0008] Furthermore, when the motor output is equal to or greater than the first intermediate output but less than the second intermediate output, pressing the first pressing unit will not increase the motor output above the second intermediate output. Therefore, when changing the motor output within the range of equal to or greater than the first intermediate output but less than the second intermediate output in response to the pull of a fish, even if the first pressing unit is pressed with more force than intended, the motor output is limited so as not to exceed the second intermediate output. In other words, the motor output can be prevented from reaching near its maximum output. This prevents the fishing line from breaking or the breaker from activating due to a heavy load on the electric reel when changing the motor output in response to the pull of a fish.

[0009] The motor control unit may maintain the motor output at the first intermediate output if the pressing operation on the first pressing unit is stopped while the motor output is limited to the first intermediate output. The motor control unit may increase the motor output above the first intermediate output when the first pressing unit is pressed while the pressing operation on the first pressing unit is stopped and the motor output is maintained at the first intermediate output. In this case, the motor output increases above the first intermediate output when the pressing operation is resumed, thereby effectively preventing the motor output from increasing more than expected by the angler.

[0010] The motor control unit may maintain the motor output at the second intermediate output if the pressing operation on the first pressing unit is stopped while the motor output is limited to the second intermediate output. The motor control unit may increase the motor output above the second intermediate output when the first pressing unit is pressed while the pressing operation on the first pressing unit is stopped and the motor output is maintained at the second intermediate output. In this case, the motor output increases above the second intermediate output when the pressing operation is resumed, thereby effectively preventing the motor output from increasing more than expected by the angler.

[0011] The motor control unit may perform adjustment control such that, if the first pressing unit is pressed while the motor output is maintained at the second intermediate output, the motor output is increased above the second intermediate output in accordance with the first pressing force, and if the pressing unit is stopped while the motor output exceeds the second intermediate output, the motor control unit decreases the motor output to the second intermediate output. In this case, the motor output can be adjusted by intuitive operation.

[0012] In the adjustment control, the motor control unit may increase the motor output as the first pressing force increases and decrease the motor output to the second intermediate output as the first pressing force decreases, which allows the motor output to be adjusted with even more intuitive operation.

[0013] The motor control device may further include a notification unit that notifies the user that the motor control unit is performing speed increase / decrease control. In this case, the user can easily recognize that speed increase / decrease control is being performed.

[0014] If the motor output when the pressing operation on the first pressing unit is stopped is equal to or less than the second intermediate output, the motor control unit may maintain the motor output when the pressing operation on the first pressing unit is stopped, which makes it easier to adjust the motor output.

[0015] The motor control device may further include a second pressing portion provided on the reel body to be pressed. The motor control unit may reduce the output of the motor in accordance with the second pressing force applied to the second pressing portion and the duration of time the second pressing portion is pressed, and maintain the motor output when pressure on the second pressing portion is stopped. This makes it easier to adjust the motor output.

[0016] The motor control device may further include a first operating unit provided on the reel body. The motor control unit may control the motor output in stages from a stopped state to maximum output. The motor control unit may be able to set any output stage between a first output stage corresponding to a first intermediate output and a second output stage corresponding to a second intermediate output in response to operation of the first operating unit. The motor control unit may interchange the first output stage and the second output stage when the first output stage is set to an output stage greater than the second output stage, or when the second output stage is set to an output stage less than the first output stage. In this case, it is possible to prevent the first output stage from being set to an output stage greater than the second output stage.

[0017] The motor control device may further include a second operating unit provided on the reel body. The motor control unit may control the output of the motor in stages from a stopped state to maximum output. The motor control device may change a first output stage corresponding to a preset first intermediate output in response to operation of the second operating unit when the motor is driven at an output less than the first intermediate output. The motor control device may change a second output stage corresponding to a preset second intermediate output in response to operation of the second operating unit when the motor is driven at an output equal to or greater than the first intermediate output and less than the second intermediate output. In this case, the set value of the first output stage or the second output stage can be easily changed while the motor is driven.

[0018] The motor control unit may stop the output of the motor when the fishing line unwound from the spool reaches the stop line length, and reset the first and second output stages changed by operating the second operating unit to the preset first and second output stages, thereby improving operability.

[0019] A program according to another aspect of the present invention causes a motor control device of an electric reel, which uses a motor to drive a spool rotatably attached to a reel body having a pressure portion that can be pressed, to perform the following processes: increasing the output of the motor in accordance with at least one of the pressure applied to the pressure portion and the duration of time the pressure portion is pressed; limiting the output of the motor to the first intermediate output until the pressing of the pressure portion is stopped, if the pressing of the pressure portion is an operation that causes the motor output to exceed the first intermediate output from a state where the motor output is less than a first intermediate output; and limiting the output of the motor to the second intermediate output until the pressing of the pressure portion is stopped, if the pressing of the first pressure portion is an operation that causes the motor output to exceed the second intermediate output from a state where the motor output is equal to or greater than the first intermediate output and less than a second intermediate output between the first intermediate output and the maximum output. [Effects of the Invention]

[0020] According to the present invention, in a motor control device for an electric reel, it is possible to prevent the motor output from increasing more than expected by an angler. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] First Embodiment An electric reel 100 embodying the present invention is an electric reel that is motor-driven by power supplied from an external power source, as shown in FIG.

[0023] The electric reel 100 includes a reel body 1, a spool 2, a motor 3, a handle 4, a counter case 5, a first pressing portion 11, a second pressing portion 12, and a motor control portion 17. The first pressing portion 11, the second pressing portion 12, and the motor control portion 17 constitute a part of a motor control device.

[0024] The reel body 1 has a frame 6, a first side cover 7 that covers one side of the frame 6, a second side cover 8 that covers the other side of the frame 6, and a front cover (not shown) that covers the front of the frame 6. Inside the reel body 1, there are arranged a level wind mechanism (not shown) that operates in conjunction with the spool 2, a rotation transmission mechanism (not shown) that transmits the rotation of the motor 3 and handle 4 to the spool 2, and the like.

[0025] The spool 2 is disposed inside the reel body 1. The spool 2 is rotatably attached to the reel body 1 between a first side cover 7 and a second side cover 8.

[0026] The motor 3 is disposed inside the reel body 1. The motor 3 is PWM controlled by the motor control unit 17, and drives the spool 2 to rotate in the line winding direction in response to the pressing operation of the first pressing portion 11 and the second pressing portion 12.

[0027] The handle 4 is rotatably supported by the first side cover 7 .

[0028] The counter case 5 is disposed on top of the reel body 1. The counter case 5 is fixed to the frame 6. The counter case 5 is provided with a display unit 10 having a liquid crystal display, a first pressing unit 11, a second pressing unit 12, and first to third operating units 13 to 15. The first to third operating units 13 to 15 are mainly used when configuring various settings for the electric reel 100. The first to third operating units 13 to 15 are operated by pressing them. The first to third operating units 13 to 15 may be touch panels provided on the display unit 10. A control unit 16 (see FIG. 2) that performs various controls is housed inside the counter case 5.

[0029] The first pressing portion 11 and the second pressing portion 12 are provided on the reel body 1 so as to be pressed. The first pressing portion 11 has a pressure sensor 11a. The pressure sensor 11a detects a value corresponding to the magnitude of the pressing force (hereinafter referred to as the first pressing force) that presses the first pressing portion 11 and outputs the value as an electric signal to the motor control unit 17. The second pressing portion 12 has a pressure sensor 12a. The pressure sensor 12a detects a value corresponding to the magnitude of the pressing force (hereinafter referred to as the second pressing force) that presses the second pressing portion 12 and outputs the value as an electric signal to the motor control unit 17.

[0030] 2, the control unit 16 has, as its functional configuration, a motor control unit 17 that controls the motor 3 and a display control unit 18 that controls the display unit 10. The motor control unit 17 controls the output of the motor 3 (hereinafter referred to as motor output) in response to a pressing operation on the first pressing unit 11 or a pressing operation on the second pressing unit 12 via a motor drive circuit 19 that PWM drives the motor 3.

[0031] The control unit 16 is connected to the first pressing unit 11, the second pressing unit 12, and the first to third operation units 13 to 15. The control unit 16 is also connected to the display unit 10, a spool sensor 20 for detecting the rotation speed and rotation direction of the spool 2, and a memory unit 21. The memory unit 21 is, for example, a non-volatile memory, and stores various setting information for the electric reel 100, such as information on the shelf position and information on the boat side stop position.

[0032] The motor control unit 17 controls the motor output in stages from a stopped state to a maximum output. The motor control unit 17 increases the motor output (e.g., the rotation speed of the motor 3) in accordance with at least one of the first pressing force and the pressing time for which the first pressing unit 11 is pressed. The motor control unit 17 decreases the motor output (e.g., the rotation speed of the motor 3) in accordance with at least one of the second pressing force and the pressing time for which the second pressing unit 12 is pressed. The motor control unit 17 in this embodiment increases the motor output in accordance with the first pressing force and decreases the motor output in accordance with the second pressing force. The motor control unit 17 maintains the motor output when the pressing operation on the first pressing unit 11 is stopped. The motor control unit 17 maintains the motor output when the pressing operation on the second pressing unit 12 is stopped.

[0033] If the pressing operation on first pressing unit 11 is an operation that causes the motor output to exceed the first intermediate output from a state where the output is less than the first intermediate output, motor control unit 17 limits the motor output to the first intermediate output until the pressing operation on first pressing unit 11 is stopped. The first intermediate output is an arbitrary output that is greater than the output in the stopped state and less than the maximum output. Note that if the pressing operation on first pressing unit 11 is an operation that causes the motor output to exceed the first intermediate output from a state where the output is less than the first intermediate output, motor control unit 17 may limit the motor output to the first intermediate output until the pressing operation on first pressing unit 11 is stopped.

[0034] If the pressing operation on first pressing unit 11 is an operation that causes the motor output to exceed the second intermediate output from a state where the motor output is equal to or greater than the first intermediate output but less than the second intermediate output, motor control unit 17 limits the motor output to the second intermediate output until the pressing operation on first pressing unit 11 is stopped. The second intermediate output is an arbitrary output between the first intermediate output and the maximum output. Note that if the pressing operation on first pressing unit 11 is an operation that causes the motor output to exceed the second intermediate output from a state where the motor output is equal to or greater than the first intermediate output but less than the second intermediate output, motor control unit 17 may also limit the motor output to the second intermediate output until the pressing operation on first pressing unit 11 is stopped.

[0035] If the pressing operation on first pressing unit 11 is stopped while the motor output is limited to the first intermediate output, motor control unit 17 maintains the motor output at the first intermediate output. If the pressing operation on first pressing unit 11 is stopped while the motor output is maintained at the first intermediate output and first pressing unit 11 is pressed, motor control unit 17 increases the motor output above the first intermediate output.

[0036] <Motor control processing> Next, an example of the flow of the motor control process performed by the motor control unit 17 of the control unit 16 when the power supply of the electric reel 100 is in the on state will be described with reference to the flowcharts shown in Figures 3 and 4. Here, the motor output is adjusted in stages from 0 to Nmax (Nmax+1 stages). Stage 0 is a state in which the motor 3 is stopped, and stage Nmax is a state in which the motor 3 is driven at maximum output. The motor output is adjusted in 31 stages, for example.

[0037] Here, lower and upper limits (e.g., lower limit 30 grams, upper limit 2 kilograms) are set for the pressure output from the pressure sensors 11a and 12a. The range between the lower and upper limits is then divided into any number of stages (e.g., 31 equal divisions), and the increments and decrements of the motor output stages corresponding to each stage are set. It is preferable to set the increments and decrements of the motor output stages so that the greater the pressure, the greater the number of increments and decrements.

[0038] In addition, the motor 3 is controlled by the PWM method, and the maximum output is a duty ratio of 100%. The motor output is, for example, the rotation speed of the motor 3. When the rotation speed of the spool 2 drops due to a load, feedback control is performed to maintain a predetermined rotation speed.

[0039] First, in step S1, it is determined whether the first pressing force P1 applied to the first pressing portion 11 is 30 g or greater. Specifically, for example, the output from the pressure sensor 11a of the first pressing portion 11 is detected to determine whether the first pressing portion 11 is pressed with a pressing force of 30 g or greater. If an output of the first pressing force P1 less than 30 g is detected, the output is ignored to avoid erroneous operation, assuming that the first pressing portion 11 is not pressed. Note that here, for example, a resistive film type pressure sensor is used, and the circuit is configured so that the output voltage is proportional to the pressing force.

[0040] If it is determined in step S1 that the first pressing force P1 is 30 g or more, the process proceeds to step S2. In step S2, the current motor output stage (hereinafter referred to as stage N) is read.

[0041] In step S3, it is determined whether the stage N is equal to or greater than a first output stage NM1 corresponding to a first intermediate output. The first output stage NM1 is preferably a stage within the range of stages 5 to 15. The first output stage NM1 is set to stage 10, for example.

[0042] If it is determined in step S3 that the stage N is equal to or greater than the first output stage NM1, the process proceeds to step S4. If it is determined in step S3 that the stage N is less than the first output stage NM1, the process proceeds to step S31 shown in Fig. 4. Details of steps S31 and onwards will be described later.

[0043] In step S4, it is determined whether the stage N is equal to or greater than a second output stage NM2 corresponding to a second intermediate output. The second output stage NM2 is preferably, for example, a stage within a range of stages 15 to 25. The second output stage NM2 is set to stage 20, for example.

[0044] If it is determined in step S4 that the stage N is equal to or greater than the second output stage NM2, the process proceeds to step S5. If it is determined in step S5 that the stage N is less than the second output stage NM2, the process proceeds to step S41 shown in Fig. 5. Details of steps S41 and onwards will be described later.

[0045] In step S5, it is determined whether the first pressing force P1 is less than 2 kg. If it is determined in step S5 that the first pressing force P1 is 2 kg or more, the process proceeds to step S13, where stage N is set as stage Nmax. That is, the motor output is increased to the maximum output. Then, the process proceeds to the next step S11, where the motor output is maintained at stage Nmax.

[0046] In addition, if the first pressing portion 11 is pressed with a first pressing force P1 of 2 kg or more while the motor output is maintained at stage Nmax, the process will proceed to step S12. However, since the motor output is already maintained at stage Nmax, the motor output will continue to be maintained at stage Nmax.

[0047] If it is determined in step S5 that the first pressing force P1 is less than 2 kg, the process proceeds to step S6, where a preset step increase number M for the output of the pressure sensor 11a is read from the storage unit .

[0048] In step S7, it is determined whether the sum of stage N and stage increment number M is less than Nmax. If it is less than Nmax, the process proceeds to step S8, where N+M is set as stage N. That is, the motor output is increased to N+M stages. Specifically, for example, if the first pressing unit 11 is pressed with a first pressing force P1 of 300g to 400g when the motor output is at stage 22, stage N is set to 24, which is the sum of the stage increment number 2 that is preset to correspond to the range of the first pressing force P1. Then, the process proceeds to step S9.

[0049] If it is determined in step S7 that the current stage N plus the stage increase number M is equal to or greater than Nmax, the process proceeds to step S12, where the stage one stage lower than stage Nmax is set as stage N. In other words, stage N will not become stage Nmax unless the first pressing force P1 on the first pressing unit 11 exceeds 2 kg. Then, the process proceeds to step S9.

[0050] In step S9, the process waits for, for example, 0.5 seconds, and then proceeds to step S10.

[0051] In step S10, similarly to step S1, it is determined whether the first pressing force P1 is 30 g or more. That is, it is determined whether the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or more. If the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or more, the process returns to step S2. If the first pressing unit 11 is not being pressed with a first pressing force P1 of 30 g or more, the process proceeds to step S11, where the motor output is maintained at the stage N set in step S8 or step S12.

[0052] If it is determined in step S1 that the first pressing force P1 is less than 30 g, the process proceeds to step S14.

[0053] In step S14, it is determined whether the second pressing force P2 applied to the second pressing portion 12 is 30 g or more based on the output from the pressure sensor 12a. If the output of the second pressing force P2 is less than 30 g, the output is ignored, assuming that the second pressing portion 12 is not being pressed, in order to avoid erroneous operation.

[0054] If it is determined in step S14 that the second pressing force P2 is 30 g or more, the process proceeds to step S14, where it is determined whether stage N is 1 or more, i.e., whether the motor 3 is being driven. If stage N is 0, operating the second pressing unit 12 to reduce output is meaningless, so the motor control process is not executed. If stage N is 1 or more, the process proceeds to step S15.

[0055] In step S15, it is determined whether the second pressing force P2 is less than 2 kg. If the second pressing force P2 is 2 kg or more, the process proceeds to step S24, where the stage N is changed to 0. That is, the driving of the motor 3 is stopped.

[0056] If it is determined in step S16 that the second pressing force P2 is less than 2 kg, the process proceeds to step S17, where the stage N is read in. Thereafter, the process proceeds to step S18.

[0057] In step S18, the number of steps L of decrease preset for the output of the pressure sensor 12a is read from the storage unit 21, and the process proceeds to step S19.

[0058] In step S19, it is determined whether the value obtained by subtracting the number of step reductions L from the stage N is 1 or greater. If the value obtained by subtracting the number of step reductions L from the stage N is 1 or greater, the process proceeds to step S20, where N - L is set as the stage N. In other words, the motor output is reduced to the NL stage. Then, the process proceeds to step S21.

[0059] In step S19, if the value obtained by subtracting the number of stages reduction L from stage N is less than 1, the process proceeds to step S23, where stage N is changed to 1. Thereafter, the process proceeds to step S21.

[0060] In step S21, the process waits for, for example, 0.5 seconds, and then proceeds to step S22.

[0061] In step S22, similarly to step S14, it is determined whether the second pressing force P2 is 30 g or more. That is, it is determined whether the second pressing unit 12 is being pressed with a second pressing force P2 of 30 g or more. If the second pressing unit 12 is being pressed with a second pressing force P2 of 30 g or more, the process returns to step S16. If the second pressing unit 12 is not being pressed with a second pressing force P2 of 30 g or more, the process proceeds to step S11, and the motor output is maintained at the stage N set in step S20 or step S23.

[0062] Next, the flow of the motor control process when it is determined in step S3 that stage N is less than the first output stage NM1 will be described with reference to Fig. 4. When it is determined in step S3 that stage N is less than the first output stage NM1, the process proceeds to step S31.

[0063] In step S31, a preset step increase number M for the output of the pressure sensor 11a is read from the storage unit 21. After that, the process proceeds to step S32.

[0064] In step S32, it is determined whether the sum of the step N and the step increment number M is greater than the first output step NM1. If the sum of the step N and the step increment number M is greater than the first output step NM1, the process proceeds to step S33.

[0065] In step S33, the first output stage NM1 is set as stage N. That is, here, the motor output is limited to the first output stage NM1 so that stage N does not exceed the first output stage NM1. Thereafter, the process proceeds to step S34.

[0066] In step S34, the process waits for, for example, 0.5 seconds, and then proceeds to step S35.

[0067] In step S35, similar to step S10, it is determined whether the first pressing portion 11 is being continuously pressed with a first pressing force P1 of 30 g or more. If the first pressing portion 11 is not being pressed with a first pressing force P1 of 30 g or more, the process proceeds to step S11, where the motor output is maintained at the first output stage NM1. If the first pressing portion 11 is being pressed with a first pressing force P1 of 30 g or more, the process returns to step S33. In other words, even if the first pressing portion 11 is being continuously pressed with a first pressing force P1 of 30 g or more, the motor output is maintained at the first output stage NM1.

[0068] If the sum of stage N and stage increment number M in step S32 is equal to or less than the first output stage NM1, the process proceeds to step S36, where the sum of stage N and stage increment number M is set as the new stage N. Thereafter, the process proceeds to step S9.

[0069] In step S32, it may be determined whether the sum of stage N and stage increment number M is equal to or greater than the first output stage NM1. That is, if it is determined in step S32 that the sum of stage N and stage increment number M is equal to or greater than the first output stage NM1, the process may proceed to step S33, and if it is determined that the sum of stage N and stage increment number M is less than the first output stage NM1, the process may proceed to step S36.

[0070] Next, the flow of the motor control process when it is determined in step S4 that stage N is less than the second output stage NM2 will be described with reference to Fig. 5. When it is determined in step S4 that stage N is less than the second output stage NM2, the process proceeds to step S41.

[0071] In step S41, a preset step increase number M for the output of the pressure sensor 11a is read from the storage unit 21. After that, the process proceeds to step S42.

[0072] In step S42, it is determined whether the sum of the step N and the step increment number M is greater than the second output step NM2. If the sum of the step N and the step increment number M is greater than the second output step NM2, the process proceeds to step S43.

[0073] In step S43, the second output stage NM2 is set as stage N. That is, here, the motor output is limited to the second output stage NM2 so that stage N does not exceed the second output stage NM2. Then, the process proceeds to step S44.

[0074] In step S44, the process waits for, for example, 0.5 seconds, and then proceeds to step S35.

[0075] In step S45, similar to step S10, it is determined whether the first pressing portion 11 is being continuously pressed with a first pressing force P1 of 30 g or more. If the first pressing portion 11 is not being pressed with a first pressing force P1 of 30 g or more, the process proceeds to step S11, where the motor output is maintained at the second output stage NM2. If the first pressing portion 11 is being pressed with a first pressing force P1 of 30 g or more, the process returns to step S43. In other words, even if the first pressing portion 11 is being continuously pressed with a first pressing force P1 of 30 g or more, the motor output is maintained at the second output stage NM2.

[0076] If the sum of stage N and stage increment number M in step S42 is equal to or less than the second output stage NM2, the process proceeds to step S46, where the sum of stage N and stage increment number M is set as the new stage N. Thereafter, the process proceeds to step S9.

[0077] In step S42, it may be determined whether the sum of stage N and stage increment M is equal to or greater than the second output stage NM2. That is, if it is determined in step S42 that the sum of stage N and stage increment M is equal to or greater than the second output stage NM2, the process may proceed to step S43, and if it is determined that the sum of stage N and stage increment M is less than the second output stage NM2, the process may proceed to step S46.

[0078] As described with reference to Figures 3 and 4, the motor control unit 17 has the characteristics shown schematically in Figure 5. In Figure 5, the horizontal axis represents the first pressing force P1, and the vertical axis represents the stage N. The dashed line C1 represents the characteristics where the motor output is limited to the first output stage NM1. The dashed line C2 represents the characteristics where the motor output is limited to the second output stage NM2.

[0079] The motor control unit 17 can set the first output level NM1 and the second output level NM2 to any output level in response to operation of the first operation unit 13. The first output level NM1 is set by, for example, operating the first operation unit 13 to switch to a setting mode for the first output level NM1 when the motor output is stopped. At this time, the display control unit 18 causes the display unit 10 to display the setting mode for the first output level NM1. Then, for example, the second operation unit 14 or the third operation unit 15 is pressed to select the first output level NM1 as any level, and the first operation unit 13 is operated again to set the first output level NM1 to the selected level. The second output level NM2 is set by operating the first operation unit 13 to switch to a setting mode for the second output level NM2, and then performing the same setting as the first output level NM1.

[0080] When the first output stage NM1 is set to an output stage greater than the second output stage NM2, or when the second output stage NM2 is set to an output stage less than the first output stage NM1, the motor control unit 17 interchanges the first output stage NM1 and the second output stage NM2. For example, when the first output stage NM1 is set to stage 10 and the second output stage NM2 is set to stage 20, if the first output stage NM1 is changed from stage 10 to stage 25, the motor control unit 17 identifies the second output stage NM2 as stage 25 and stage 20 as the first output stage NM1. In other words, the motor control unit 17 controls the set values ​​of the first output stage NM1 and the second output stage NM2 so that the first output stage NM1 is always a smaller output stage than the second output stage NM2.

[0081] When the motor 3 is driven at an output less than the first intermediate output, the motor control unit 17 changes the preset first output stage NM1 in response to the operation of the first operating unit 13 or the second operating unit 14. When the motor 3 is driven at an output equal to or greater than the first intermediate output and less than the second intermediate output, the motor control unit 17 changes the preset second output stage NM2 in response to the operation of the first operating unit 13 or the second operating unit 14.

[0082] Specifically, when the motor 3 is driven at an output stage less than the first output stage NM1, the motor control unit 17 decreases the first output stage NM1 by one stage each time the first operating unit 13 is operated, and increases the first output stage NM1 by one stage each time the second operating unit 14 is operated. When the motor 3 is driven at an output stage equal to or greater than the first output stage NM1 and less than the second output stage NM2, the motor control unit 17 decreases the second output stage NM2 by one stage each time the first operating unit 13 is operated, and increases the second output stage NM2 by one stage each time the second operating unit 14 is operated. Note that the motor control unit 17 may also control the motor 3 to increase the first output stage NM1 by one stage each time the first operating unit 13 is operated, and decrease the first output stage NM1 by one stage each time the second operating unit 14 is operated. The same applies to the second output stage NM2.

[0083] When the fishing line unwound from the spool 2 reaches the stop line length, the motor control unit 17 stops the motor output and resets the first output stage NM1 and second output stage NM2, which were changed by operating the first operating unit 13 or the second operating unit 14, to the preset first output stage NM1 and second output stage NM2. The stop line length is the line length at which the motor output is stopped, and is set, for example, to a position where the tackle attached to the fishing line is easy to grab. For example, the motor control unit 17 sets the stop line length to the line length when the third operating unit 15 is pressed and held.

[0084] In this electric reel 100, if motor output stage N is below first output stage NM1, pressing the first pressing portion 11 will not increase motor output stage N above first output stage NM1. Therefore, even if the first pressing portion 11 is pressed with a first pressing force greater than intended when the motor output is below first output stage NM1, the motor output will be limited so as not to exceed first output stage NM1. This makes it possible to prevent the motor output from increasing more than the angler expected.

[0085] Furthermore, when the motor output stage N is equal to or greater than the first output stage NM1 but less than the second output stage NM2, the motor output will not increase above the second output stage NM2 even if the first pressing unit 11 is pressed. Therefore, when changing the motor output within the range of equal to or greater than the first output stage NM1 but less than the second output stage NM2 in response to the pull of a fish, even if the first pressing unit 11 is pressed with a first pressing force greater than intended, the motor output is limited so as not to exceed the second output stage NM2. In other words, the motor output can be prevented from reaching near its maximum output. This prevents the fishing line from breaking or the electric reel 100 from being overloaded and causing the breaker to trip when the motor output is changed in response to the pull of a fish.

[0086] <Other embodiments> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0087] 7 shows characteristic C3 of the adjustment control mode of the motor control process according to the modified example. In this modified example, the motor control process performed by the motor control unit 17 in the range from the second output stage NM2 to the stage Nmax is different from that in the above embodiment. The rest is the same as in the above embodiment.

[0088] As shown in Figure 7, the adjustment control mode is a control mode in which, if a pressing operation is performed on the first pressing unit 11 while the output stage of the motor 3 is maintained at the second intermediate output (here, the second output stage NM2), the motor output is increased above the second intermediate output in accordance with the first pressing force P1, and if the pressing operation on the first pressing unit 11 is stopped while the motor output exceeds the second intermediate output, the motor output is reduced to the second intermediate output.

[0089] In the adjustment control mode, the motor control unit 17 increases the motor output in response to an increase in the first pressing force P1, and decreases the motor output to the second intermediate output in response to a decrease in the first pressing force P1.

[0090] In the adjustment control mode, the output stage of the motor 3 is increased above the second output stage NM2 in accordance with the first pressing force P1 only while the first pressing portion 11 is being pressed, and if the first pressing portion 11 is not being pressed, the motor output is reduced to the second intermediate output and the output stage of the motor 3 is maintained at the second output stage NM2.

[0091] The motor control unit 17 cancels the adjustment control mode when the output stage of the motor 3 decreases below the second output stage NM2 in response to the pressing operation of the second pressing unit 12 during the adjustment control mode.

[0092] 8, the display control unit 18 causes the display unit 10 (an example of a notification unit) to display that the motor output is being controlled in the adjustment control mode. While the adjustment control mode is being executed, the display control unit 18 causes the display unit 10 to display, for example, "Boost." When the adjustment control mode is released, the display control unit 18 causes the display unit 10 to stop displaying "Boost." Note that the notification means for notifying that adjustment control is being executed may be another means such as light, sound, or vibration.

[0093] In the modified example, the adjustment control mode is executed in the range from the second output stage NM2 to the stage Nmax. However, for example, the adjustment control mode may be executed in the range from the first output stage NM1 to the second output stage NM2. In this case, the maximum output stage in the adjustment control mode is the second output stage NM2. That is, an upper limit for the output stage may be set in the adjustment control mode. After the second output stage NM2 is reached, the same motor control processing as in the above embodiment is executed. The maximum output stage in the adjustment control mode may be an output stage smaller than the stage Nmax and different from the second output stage NM2.

[0094] The positions of the first pressing portion 11 and the second pressing portion 12 may be interchangeable. Alternatively, the functions of the first pressing portion 11 and the second pressing portion 12 may be interchangeable depending on the operation of the first to third operating portions 13 to 15.

[0095] In the above embodiment, the motor output was adjusted using two pressing parts, the first pressing part 11 and the second pressing part 12. However, the motor output may also be adjusted by providing a single pressing part that can switch between two modes, for example, an output increase mode in which the motor output is increased and an output decrease mode in which the motor output is decreased.

[0096] The pressure sensors 11a and 12a may not be individual components such as pressure-sensitive elements, but may be those that output in response to minute displacements of members pressed by springs with large spring constants.

[0097] In the above embodiment, the rotation speed of the spool 2 is detected as the motor output and feedback controlled, but the current value supplied to the motor 3 may be controlled so that the winding torque becomes a predetermined value. Alternatively, the line diameter wound on the spool 2 may be calculated and the tension may be controlled to a predetermined value.

[0098] In the above embodiment, the control method for rotating the motor 3 in accordance with the electrical signals output from the pressure sensors 11a and 12a may be selectable from two methods: control at a predetermined spool rotation speed, or control at a predetermined torque value.

[0099] In the above embodiment, when the range between the upper and lower limit values ​​of the pressure force output from the pressure sensors 11a and 12a is divided into arbitrary stages, the range does not have to be divided equally. The range of the pressure force corresponding to the stage with a low number of step increments and step decrements of the output stage of the motor 3 may be larger than the range of the high step increments and step decrements.

[0100] In the above embodiment, the lower and upper limits of the pressure detected by the pressure sensors 11a and 12a (for example, a lower limit of 30 grams and an upper limit of 2 kilograms) are set in advance, but the lower and upper limits, i.e., the threshold values ​​of the pressure, may be set arbitrarily by the angler. In this case, when the first pressing unit 11 and the second pressing unit 12 are operated with a pressure equal to or greater than a predetermined value while the motor 3 is stopped, the device may enter a pressure setting mode in which the threshold value of the pressure is set.

[0101] In the above embodiment, whether or not the first pressing portion 11 is operated is determined followed by whether or not the second pressing portion 12 is operated. However, the outputs of both pressure sensors 11a and 12a may be compared, and the one with the larger output, i.e., the larger pressing force, may be determined to be the valid pressing operation.

[0102] A program for realizing the motor control processing of the motor control unit 17 described above may be recorded on a computer-readable recording medium, and the motor control processing may be performed by, for example, a CPU (Central Processing Unit) executing the program recorded on the recording medium.
